BatterySqueezer free Description:
BatterySqueezer throttles selected resource hungry applications when in the background. This can reduce their CPU load which many users find beneficial.
HOW DOES IT WORK?
Applications, especially internet browsers, can put a heavy load on your system by demanding processing power even if they are running in the background.
BatterySqueezer throttles Flash animations, videos, advertisements and virtually everything that your browser runs when it is in the background.
BatterySqueezer currently throttles: Safari, Chrome, Firefox, Opera and their plugins including Flash, Office apps, Preview and App Store.
BatterySqueezer is a low footprint application. It runs discreetly on the menu bar and its dock icon can be hidden.
NOTE: BatterySqueezer only stops apps when they are in the BACKGROUND. For instance, if the user actively uses Safari/Chrome etc. (their windows on the top) it will only reduce their load when they become inactive. If the user switches from Safari/Chrome to MS Word, then MS Word becomes active and Safari/Chrome will be paused with their load dropping to almost nil. And vice versa.
If you watch a flash/HTML5 video in your browser and switch to another app, the video will be paused and its load drops to almost nil. It is recommended to pause a video if you are not watching it.

be the ticket...”
